A person can be enjoyable company and still be unreliable with a shared responsibility.

Charm and dependability are separate traits that people persistently treat as one. Someone can be genuinely warm, funny and a pleasure to spend an evening with, and also be the person who forgets the deposit. The disappointment lands harder because the friendship implied a promise it never actually made.

When you plan something with a friend, decide what depends on them and how much of it you can carry if it slips. Keep the parts with real consequences in your own hands. Liking someone is a good reason to keep the friendship out of a job it cannot hold.
